The attenuation length measuring device was constructed by using oscilloscope and LabVIEW for signal acquisition processing. performance of the has been tested with a variety ways, test results show that set-up good stability high precision (sigma/mean reached 0.4 percent). Besides, accuracy measurement system will decrease about 17 percent if filter is used. gadolinium-loaded liquid scintillator (Gd-LS) measured as 15.10 plus or minus 0.35 m where Gd-LS heavily used in Daya Bay Neutrino...
High-purity germanium (HPGe) detectors are well suited to analyse the radioactivity of samples. In order reduce environmental background for an ultra-low HPGe spectrometer, low-activity lead and oxygen free copper installed outside probe shield from gamma radiation, with outer plastic scintillator veto cosmic rays, anti-Compton detector improve peak-to-Compton ratio. Using Geant4 tools taking into account a detailed description detector, we optimize sizes these reach design requirements. A...
Liquid scintillator (LS) will be adopted as the detector material in JUNO (Jiangmen Underground Neutrino Observatory). The energy resolution requirement of is 3%, which has never previously been reached. To achieve this resolution, light yield liquid an important factor. PPO (the fluor) and bis-MSB wavelength shifter) are two main materials dissolved LAB. study influence these on transmission scintillation photons LS, 25 12 cm-long quartz vessels were used a experiment. LS samples with...
THGEMs based on a ceramic substrate have been successfully developed for neutron and single photon detection. The influences thermal scattering internal radioactivity of both FR-4 substrates were studied compared. are homemade, 200 μm hole diameter, 600 pitch, thickness, 80 rim, 50 mm×50 mm sensitive area. with the same geometry used as reference. gas gain, energy resolution gain stability measured in different mixtures using 5.9 keV X-rays. maximum layer THGEM reaches 6×104 1.5×104 at...
Types 316 and 304 stainless steel are two candidates for the storage vessels piping systems of LAB-based liquid scintillator (LS) in JUNO experiment. LS aging experiments carried out at temperatures 40 °C 25 °C. After 192 days °C, attenuation length was reduced by 6% a glass container, 12% type tank, 10% tank. At tanks, after 307 days. The light yield absorption spectrum were practically same as that unaged sample. concentration element Fe did not show clear change. Type can be used...
New types of Thick Gaseous Electron Multipliers (THGEMs) made PCB-type substrates, including Ceramic, Kapton, PTFE, and in addition to FR-4, were developed for applications requiring low neutron absorption, scattering, natural radioactivity, such as the THGEM-based detector, gaseous multiplier (GPM). Using Geant4 simulation, result total absorption scattering ratio bare substrate is Kapton(high) > FR-4 Ceramic PTFE (low). The substrates have lower ratios about 0.707% 0.635% per layer(0.2 mm...
Ovarian cancer is a malignant tumor with different clinicopathological and molecular characteristics. Due to its nonspecific early symptoms, the majority of patients are diagnosed local or extensive metastasis, severely affecting treatment prognosis. The occurrence ovarian influenced by multiple complex mechanisms including genomics, transcriptomics, proteomics. Integrating types omics data aids in predicting survival rate patients. However, existing methods only fuse multi-omics at feature...
Audio-visual video parsing (AVVP) aims to recognize audio and visual event labels with precise temporal boundaries, which is quite challenging since or modality might include only one label the overall available. Existing denoising models often treat process as a separate preprocessing step, leading disconnect between AVVP tasks. To bridge this gap, we present novel joint reinforcement learning-based approach (RLLD). This enables simultaneous training of both through optimization strategy....
In this work, we study the response of a single layer Thick Gaseous Electron Multiplier (THGEM) detector to p/π+ at E3 line Beijing Test Beam Facility. The THGEM drift gap used in is 4 mm, and gain operated Ar+3% iC4H10 about 2000. particles momenta between 500 MeV/c 1000 are distinguished by Time Of Flight system. Our results show that measured momenta, detection efficiencies for p from 93% 99%, π+ range 82%–88%. Meanwhile, simple Geant4 simulations also have been done, consistent with...

Stainless steel is the material used for storage vessels and piping systems of LAB-based liquid scintillator in JUNO experiment. Aging recognized as one main degradation mechanisms affecting properties scintillator. aging experiments were carried out different containers (type 316 304 stainless glass) at two temperature (40 25 degrees Celsius). For continuous tests, light yield absorption spectrum are nearly same that unaged one. The attenuation length aged samples 6%~12% shorter than But...
A novel 2-D cosmic ray position detector has been built and studied. It is integrated from a CsI(Na) crystal pixel array, an optical fiber image intensifier ICCD camera. The positions of one track determined by the location fired pixel. scintillation light these 1.0×1.0 mm pixels delivered to through fibers. information recorded in camera form images, which can be reconstructed. background noise images have study shows that detection efficiency reach up 11.4%, while false accept rate less than 1%.
Double layers of 150 mm?150 mm plastic scintillator arrays are used to locate the cosmic ray. Both read out by wavelength-shifting fibers, which bundled and coupled image intensifier ICCD camera. The light signal is delayed more than 200 ns intensifier, so can be pre-triggered an external fast coincident signal. This ray positioning system measure time resolution photon transfer time-of-fly detector for common test platform based on Compared with traditional rays test, data-taking efficiency...
